After taking an ass-load of measurements with the subframe in the car and the diff shimmed up in the place I thought it needed to go, I recreated the whole thing on a bench and started making the mounts. It seriously took me probably 10 hours of just measuring and shimming and moving and measuring to get the diff where I wanted it in the car, then again on the bench. Making and welding the mounts probably only took 4 or 5.
